FI Check Printing

Hi Gurus,

I am developing check printing form using SAP Scripts. I copied standard SAP script F110_prenum_chck into z form. Our requiriement to print only check so i commented other code like payment summary. Whenever we try to print check the we are getting 3 pages. On the first page we are getting some symbols like 'XXXXXXXXXXXXXXXXXXXXXX' . In second page i am getting the actual data of check like amount, check no etc and in third page i am getting form summary section. Even i commented all the code of my form even though i am getting 3 blank pages. Is this related to config issue. Please help me.
